I think that MC has done more harm than good. He doesn't sound pro-marriage if he's talking about S. If it were me, I'd stop going to him and put that money on a DB Coach. Your W isn't going to listen to any counseling right now b/c she thinks "you" are the problem.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
